To @ZZ whom it may concern.

Be it known that l, CHARLES B. WoonwoRTH, a subject of the King of Great Britain, residing at Niagara Falls, in the county of Niagara and State of New York, have invented a new and usetullmprovement in Spring-Covers, of which the' following is a speciic'ation. l

'llhis invention relatesto spring covers of the kind used on'automobiles or other vehicles to cover the springs and keep the same.

lubricated.

The objects of this invention are to produce a spring cover which is so made that it will fit springs of a number of dierent sizes; also to provide spring covers of this kind with fastening devices of new and improved construction; also tov improve the construction of spring covers b providing means for closing the ends of tiie covers so as to exclude water and other foreign matter and to retain the lubricant in the cover;

. ing the invention, one of thecovers beingl shown in section.

Fig. 2 is a top plan view thereof, showing the outer layer of one ofl the covers removed.

Figs. 3 and 4 are itraentary transverse sectional views onan enlarged scale on lines 3 3 and 4--4 Fig. l.

lig.- 5 is a fragmentary sectional perspectived view thereoi:l showing the securing devices and the manner of fastening the same to the cover.

A; represents oneof the springs rot a vehicle which may be secured to the traine Af of the vehicle in any desired manner. The spring,. as usual, consists of a plurality et leaves which are secured together at their middle lport-ions by means of the usual clamps B and spring clips C are also preferably used to hold the leaves of the Spring Specicati'ono Letters Patent.

together. `All of these parts-'may be of any usual or suitable construction and of them-" `material and an inner pad or lining E of eltor other absorbent material, the ends of p v y the. outer casing being turned over the edges of the pad as shown at d and one side edge of the casing bein turned over the corresponding edge of the felt as 4shown at 02"', so

that when the cover is in place no parts of the felt pad will be visible or exposed. rllhe outer casing or covering may be made of oil cloth, imitation leather or of any other material vwhich will be more or less impervious to water and oil sothat the'casing will serve the purpose of excluding water or other toreign matter from the spring and will also keep the 4oil in the pad ory inner layer of the,

spring cover. The pad is preferably made of felt but any other material which will absorb oil or other lubricant and transmit it to the spring leaves may be used.

'The spring cover is ,preferably made of such form as to extend around the spring and the oppositeside edges thereof are then overlapped and secured'together, as shown in Fig. 6. rl`he means for securing the edges together (are preferably constructed as follows ling one edge of the spring cover,

preferably along 'the edge -on which the outer covering is turned over as shown at d', a plurality of hooks l? are secured to the spring cover in any suitable manner, for eX- ample, the hooks may be formed by bending over the ends of staples or U-shaped members f, the legs oic which extend through the bent over edges .of the outer covering and the body portions of which are arranged within the folded edge oi' the outer layer or casing of the cover, as shown in Fig. tl. 'llhe y i ends of the legs of the sta les 'are bent over to forni the hooks F which penetrate the yother 'Side of the casing and4 thereby hold the cover in place on a spring, v ln order to hold thestaples. in place in the outer casing of the cover, rivets f are preferably used which are placed immediately in back of the staples and which serve the further purposes of securing the casing and the pad of the cover together and of holding' the turned i over portions-al" in place. Since the .hoolrs can en age any portion of the cover, it willl be evi ent that a cover which `is wider than necessary can be readily applied to a spring `1 lill' l insonne by overlapping the edges oi the cover to a greater or less extent. Consequently it is not necessary to make a special sized cover ior every ditierent spring, since one size oi y cover can be used on a plurality oi sizes oi springs. This greatly sirnplies the marlreting of these covers, since dealers are not obliged'to havev on hand as many diferent sizes of covers lto meet thedcustonoers dernands, as is the case with covers which must ht a spring accurately in order to be useful.

lin order to have the'spring covers present a neat appearance -when secured toa spring, it is desirable to eliminate or correct as inuch as possible 'the projection or unevenness caused by the spring clips. This is acceuiplished by cutting avvaylparts et the pad or inner layer oi the spring cover as shown at Gr, lfigs. l and 2, at the points 'where the spring clips are located or Where otherl project-ing parts oi the spring occur. Since the 'tivo layers oi the spring covers aire secured together at one edge et the cover, the cutting away oi parts oi the inner layer will not disconnect the tivo parts oi the cover., By of" this cutting away ot parts oi the felt or inner layer? the projections which would otherwise occur on cover when place on the spring are either entirely eliminated or else greatly reduced9 so that with the cover in place presents a neat appearance.

ll/leans are also preierably provided "lor securing the end portion oi'the cover to the spring so'as to hold the cover securely in place and prevent or other ioreign' matter from entering between the cover spring at the oi? oe cover. iny suitable ineens be iior this pun pose, Y nibers lil being preierably provided are noade oi a shap^ adapted to all portions oi ends o the cover tightly the spring.. These clarnps are preferably niade oii Inetal and are so formed they will securely the ends oli/the cover all tour oi the spring thus positively the passage oi oil or water beyond the ends oi the cover. lin the construction shown the clamps are made oi a single piece ot metal bent to contorni to the shape oi' the spring and the ends thereoiz are connected by'noeens oi a bolt or the it., v u

llt is also desirable toprovide means for lubricating the spring without necessitating the rernoval of the cover :buona the This is accomplished in the construction shown by )ineens of a pertorated tube or oon-` durt K, 'which is preferably arranged between the tivo layers or ports oi the spring cover.

'll'he tube K inthe construction doovvn has a receiving end llc which ext/ends outthrough the outer casing of the cover into a, position whichoil or other lubricant may be easily initrd-unid ini@ the' et ne such for example as a cap le.

lholding the tube in place mays however, be

used. 'l` his tube is preferably made loi a duct-ile metal `which will not be injured by the dering or yielding oi the spring. By introducing the oil through the tube-it is distributed substantially throughout the length oi the spring cover and saturatesthe felt so that the lubricant will be supplied to all parts of the spring., l@2t-her -neans torintroducing lubricant niay 'beprovided it desired.

The spring covers shovvn keep the springs ivell lubricated so that the springs at all tunes will yield rreely and vvill not stiden up due to the rusting oi the leaves or to the ex cessive friction between leaves caused by the introduction oi grit or other L'oreign matter between `the leaves.J The spring covers present a neat appearance when in place on the spring and vto a certain extent hide the projecting parte7 such as spring cli-ps, ovving to the cutting away or omitting parts oi the pad.' The fastening' devices described are particularly desirable since the two longitudinal edges of the spring cover can overlap to any desired extent, so that one size oi cover niay be used on springs oi'a number oi diilerent sizes. Periorating the casing by-rneans of the hooks does not injure the cover since it is seldom necessary to remove the spring cover7 the lubrication being ediected through the perforated tube. Pl'his tube has 4the advantage oi distributing the lubrito all parts oi the spring through the naediinn ofthe pad. 'llhe rigid end clarnps lll@ ica

are very nouch rnore desirable than straps'.

or other denible end closing devices since.
